IPC: D06F83/00
Filed: 1935-03-04
Abstract: 445,808. Ironing machines. MOTTRAM, L. E., 1329, Bristol Road South, Birming- ham, and BAKER PERKINS, Ltd., Westwood Works, Peterborough. March 4, 1935, No. 6674. [Class 138 (ii)] The base convolutions 3 of the helical springs 4 of the padding of ironing-presses or ironing-rollers are received in channel members which may be formed by the bent-over edges 2 of strip material 1. Each strip includes at least three springs whereby after removal of a defective intermediate spring the remaining springs may be pushed up from one end and a new spring inserted at that end. Separate springs may be used or springs may be connected together by the wire of one spring running into another. Rotation of the springs within the strips is prevented by forming a tail piece 3a on the springs. The strips may be secured directly to the base as by screws or they may be secured to a framework which fits over and is secured to the base. The ends of the strips are closed by insertion pieces or by pinching down the sides of the channel. Alternatively the channels may be formed by U-shaped strips 7, Fig. 8, secured to the roller or buck and having outwardly turned legs 8, or in another form, Fig. 9, the bed of the buck or roller is grooved and flat strips 11 are secured to the remaining ribs 10 to form the channels.

Abstract: 525,838. Gun sights. I.S.S.A. INDUSTRIA SPECIALIZZATA STRUMENTI AERONAVIGAZIONE SOC. ANON:, and LANCIANI, E. March 1, 1939, No. 6759. Convention date; March 1, 1938. [Class 92 (ii)] Relates to open sights for guns mounted on fast-moving vehicles in which the angle between the gun and sight is automatically corrected for " own " speed as the gun is trained. According to the invention, the back-sight bead 12 is mounted on a cross-bar 11 joining two crank arms 9, 10 which are geared with the training mechanism by a shaft 8 and internal gear wheels 5, 6, 7 as shown in Fig. 3 so as to remain parallel to the direction of movement of the vehicle for all positions of gun training. The radius of the crank arms is adjustable by slides such as 9<SP>1</SP> to suit the vehicle speed and the arrangement is such that, during gun training, the bead 12 moves in a circular path with centre O on the elevating axis 13 of the gun. The foresight frame c shaped as shown in Fig. 5 for introducing corrections for enemy speed, is mounted on the gun at a fixed distance d from O representing the vector of the projectile velocity, the distance 12, O representing the vector of vehicle speed. It follows therefore that the line from 12 to the centre 15 of the foresight gives the corrected sight line for " own speed." the correction for enemy speed being obtained by sighting the aircraft as it enters the circular edge of the frame c.

Title: Improvements in or relating to synchronized asynchronous machines
IPC: H02K17/26
Filed: 1923-03-08
Abstract: 196,586. Compagnie GÚnÚrale Electrique. April 22, 1922, [Convention date]. Motors, controlling; exciting.-A synchronous induction machine is constructed with the stator as field magnet and the rotor as armature and is provided with a continuous-current commutator winding on the rotor in addition to the polyphase minding, the stator winding being of the star three-phase type, two of the phases being excited from the continuous-current winding at synchronous speed, while the third is short-circuited for damping; the commutator brushes are set back 60‹ from the neutral line at no load. The continuous-current winding C, Fig. 4, is connected in series with the stator phase winding 3. The machine is started up by gradually diminishing the resistances r<1>, r<2>, r<3>, and when these have been eliminated the short-circuit across the phasewindings 1 and 2 is replaced by a short-circuit across the phase-winding 1, Fig. 6. The phasewindings 2, 3 are thus left in series with the continuous-current winding and the winding 1 acts as a damping winding. If it is desired to reverse the direction of rotation of the machine, the winding C is connected to the phase-winding 1, and for synchronous running the phase-winding 3 is short-circuited and the two windings 1 and 2 connected in series with the winding C. The resulting flux is thus shifted 120‹ so that no movement of the brushes on the commutator C is necessary. The starting of the machine may be controlled by a three-armed switch.

Title: Apparatus for recording physical or chemical values or for controlling a movable part at a distance
IPC: G08C19/16
Filed: 1923-03-10
Abstract: 194,717. Roucka, E. March 10, 1922, [Convention date]. Tell-tale apparatus in which a force or movement to be recorded co-operates with a periodically varying auxiliary force or movement so as to produce, when a given relation exists between them, an impulse of energy, the position of which in a time interval determines the operation of recording mechanism at the receiving station, is characterized by the use of synchronous motors at the two stations. A motor 56, Fig. 1, at the transmitting station drives continuously through gearing an insulated disc 20 having an extension 10 carrying a contact 12. At the receiving station a synchronous motor 70. 72. drives similarly an arm 88 with a recording end 90. Once in each revolution the contact 12 touches the pointer 6 of a measuring instrument, and a circuit is completed over one of the supply leads 58 to energize magnet 102 at the receiving station so that the arm 88 is pressed momentarily on to the record strip and makes a dot thereon. The arm 10 also carries two contacts 14 which co-operate with a spring 16 so as to send once in a revolution two impulses in quick succession. This results in a double row of dots 93 on the record strip which forms a line of reference for the graph 94. Adjustments of phase between the arms 10 and 88 are carried out by means of one or other of two differential gear arrangements through which their respective motors drive them. The frame carrying the wheels 28, 30 carries a toothed ring which cooperates with a pinion 32 rotatable by a handle 38. The handle 38 is clamped in any position by a nut 40 which engages a disc 36 fast with the shaft 34. In another arrangement, Fig. 3, a reversible motor 156 is driven under control of a clock-controlled reversing switch 174, 176, 178 and drives a three-phase generator 158 and a drum 148. A pin 184, carried by the drum 146. at the end of each rotation in either direction interrupts at contacts 180 the circuit of the motor 156 which stops until the movement of the arm 178 completes a circuit for driving it in the other direction. The generator 158 drives synchronously a motor 192 at the receiving station, and this drives an arm 200 with a recording point 206. The drum 148 continuously varies the tension of a spring 146 connected to a lever 128 the other end of which is connected to a Bourdon tube 120. When equilibrium is attained, both when the tension of the spring 146 is increasing and when it is decreasing, the arm 128 leaves one of the stops 132, 134 and moves to the other, operating in passing, a switch arrangement 130, 140. 142, whereby a momentary impulse is sent to the receiving station to energize magnet 214 and cause the point 206 to be pressed on to the record strip. Specifications 191,395, 191,728. 191.729. 191,730, 191,735, 191,736, 193,398, and 193,841 are referred to.

A pressure-regulating slide valve for producing by throttling action a regulated pressure linearly dependent on a speed of rotation has a body 14, Fig. 1, subject in one direction to the regulated pressure and in the other direction to a force which is dependent on the speed and is produced by the torque developed in an eddy-current device 24, Fig. 2. The latter is connected to the valve body either through a rack and pinion 20 or through a push rod mechanism (not shown) and the movement of the valve is resisted both by the regulated pressure in a duct 17 acting on the difference in area between two lands 12,13 and by an adjustable spring 27 which may be replaced by a spring located above the valve or by a torsion spring 31 on the eddy current device. In Fig. 4, the input member 112 of the eddy current device is driven by worm gearing 114 which the output member 116 is connected to the valve body by a push rod 115, a device 120 similar to a one-way clutch causing axial movement. Feedback pressure is applied to the end of the valve through a bore 131 communicating with the outlet port 130. In a further construction, a rolling bearing is inserted between the parts of the eddy current device and the valve is interposed between the latter and the worm gearing.

Abstract: 180,450. Constantinesco, G. March 5, 1921. Fluid-actuated valves.- A horn &c. actuated by the suction of an internal combustion engine is provided with a reservoir l communicating with both the trumpet a and the induction pipe h of the engine through a valve f which controls the two passages in such a manner that during normal running the horn is actuated by the suction of the engine and a vacuum is produced in the reservoir l whilst when the engine suction is insufficient to operate the horn the suction created by the vacuum in the reservoir is utilized for this purpose. The valve f consists of a cylindrical chamber having at one end a connection g to the induction pipe h, at the other end a connection k to the reservoir l, and at the side a third connection e leading to the horn a through a controlling device b similar to that described in Specification 181,103. Two valve members r, s are mounted on a common spindle t. When the engine suction is normal the disc r is drawn away from its seating but air is sucked from the reservoir l to create a vacuum therein through small apertures u. If the suction in the pipe a falls, due for instance to the throttle being fully opened, the valve r shuts down and the valve s opens. rendering the suction in the reservoir available for operating the horn.

Title: Improvements in film propelling mechanisms
IPC: G03B19/18
Filed: 1947-03-14
Abstract: 629,011. Kinematograph apparatus. WESTERN ELECTRIC CO., Inc. March 14, 1947. No. 7152. Convention date, April 10, 1946. [Class 97 (i.)] A film propelling mechanism comprises an electric motor for driving the film, a switch adapted to close and open the motor circuit, film-engaging means movable into engagement with the film, and switch-operating means associated with the film-engaging means, the film-engaging means being arranged, in a retracted position, to allow the switch to remain open in order to permit threading of the film, in a second position, to close the switch when the film-engaging means is moved from its retracted position into engagement with the film, and, in a third position, to open the switch upon further movement in the same direction of the film-engaging means when the film is removed or exhausted, is characterized in that the switch operating means includes means movable to a non-operating position to maintain the switch open when the film-engaging means is being returned from its third position to its retracted position. As shown, a microswitch 29 is actuated by means of a pawl 21, Fig. 3, having a pivoted and spring connection with an arm 16 from which projects a pin 22 passing through a bifurcated end of the pawl to prevent lateral movement thereof on the arm and to limit pivotal movement thereof in one direction around arm 16. This arm is carried by an arm 17 pivotally mounted at 18 on a housing 7 carried by a plate 2; arm 16 carries a roller 27 which may thus be moved into contact with a film as it passes over a roller 12, carried on an arm parallel with arm 16, and into a recess 13, Fig. 3, in roller 12 when there is no film between rollers 12 and 27. Normally, roller 27 lies away from roller 12 and the pawl 21 is not engaged with a spring blade 34 which actuates the switch 29. This position of roller 27 allows threading of the film. Thereafter, arm 16 is rocked until roller 27 contacts the film with the result that pawl 21 raises the blade 34, Fig. 4, whereby the switch 29 is closed and the motor energized; a spring 24 connected to the arm 16 and housing 7 maintains the roller 27 in contact with the film and, when the film is exhausted, causes further movement of roller 27 into the recess 13 of roller 12, such movement causing disengagement of the pawl 21 from the blade 34 and consequent stoppage of the motor. When the arm 16 is rocked to its retracted position, pawl 21 contacts the end of blade 34, which rotates it until the pawl is caused by a spring 23 connected thereto to snap back to its normal position; the movement of blade 34 due to the pawl is, in this case, insufficient to actuate the switch. Arm 16 is held in its retracted position by the spring 24.
